Re: Jurassic Croc Found With Fish Like Tail
Right. I would like to know more of how such a fossil skeleton would
appear to ordinary observers.
Even though scales are not preserved in most cases, many of the
Native American stories about water monsters refer to scales, or a
lizard-like skin, or "scaly armor," and their images often include
this feature. I think this is because they related the fossil to
living snakes and lizards and to water creatures that they knew,
fish, alligators, etc.

Scales are not preserved -- in fact, as carbonized soft-tissue
remains from Germany show, the metriorhynchids had lost them (like
the ichthyosaurs). The tail is like an ichthyosaur's, too -- that is,
the vertebral column is kinked downwards. In the absence of soft-
tissue remains, few people will guess that the part behind the kink
supported the lower lobe of a forked tail fin.
The head is hard to get wrong, however! You may well be right just
because of this alone.
